The standard helmet mount issued by Army Aviation supplies has
several weaknesses that result in breakage and lack of service. Feedback
from the ALSE community and the service and repair depots from both the
military and commercial aviation have identified specific issues which
require service repair or replacement.
The front goggle receiver port on the standard mount is created with
thin molded plastic parts and assembled. The side supports that secure
the NVG in place and provide upward stowage are weak and will break at
approximately 17 lbs force on side impact. In addition, the cable is
routed into the mount at several different points on each side of the
mount and may create a snag hazard. Moreover, the black wire will
frequently pull out of the mount and render the mount and NVG
The Rugged ANVIS Mount (RAM) was designed to
overcome those weaknesses and provide a more rugged and reliable helmet
mount. The major support components in the RAM mount are machined from a
stronger material instead of using thin injection molded pieces. As a
result, the unit will withstand greater than 100 lbs force on side
impact, considerably more than most pilots or crew will require and more
than five (5x) times the standard mount.
In addition, the RAM is designed with better cable
management that routes all conductors through a single shielded cable
until it enters the main support to eliminate snag hazards and simplify
wiring. Moreover, the routing eliminates the issue of any wires pulling
out of their contact points.
The RAM helmet mount provides the unique 4-contact
receiver for the ANVIS NVG with the ball-plunger interface which
provides power to the devise.
The RAM helmet mount provides optimum translation from the
operational (down) position to the stowed (up) position while
maintaining a low profile on the user's helmet and provides vertical
adjustment for NVG alignment to the user's eyes.
The RAM mount uses a 4" shielded cable to connect with the low
profile battery pack usually located on the back of the helmet and can
be routed along the side or top of the outer surface of the helmet.
